VBScript Constants

VBScript Constants

A constant is a meaningful name that takes the place of a number

or string and never changes. VBScript currently has no constants

defined by the language. In VBScript, constants are implemented

as literal values assigned to variable names.

Creating Constants

You create constants in VBScript using the Const statement. Using the

Const statement, you can create string or numeric constants with

meaningful names. You can then assign them literal values and use

them in your script. For example:

Const MyString

MyString = "This is my string."

Const MyAge

MyAge = 49

Note that the string literal is enclosed in quotation marks (" ").

Quotation marks are the most obvious way to differentiate string

values from numeric values. Date literals and time literals can be

represented by nclosing them in number signs (#). For example:

Const CutoffDate

CutOffDate = #1-1-96#

Since there is no functional difference between constants created in

this way and regular variables, you may want to adopt a naming

scheme to differentiate constants from variables. This will prevent

you from trying to reassign their values while your script is

running. For example, you might want to use a "vb" prefix on your

constant names, or you can name your constants in all capital

letters as recommended in VBScript Coding Conventions. In either

case, it is a good idea to differentiate constants from variables. This

eliminates confusion as you develop more complex scripts.
